Instead, the coauthors hold out the promise of “safer nuclear energy systems” that will somehow turn things around. But, as NRDC’s Tom Cochran and Ralph Cavanagh point out in a recent article on the CNN website the global history of the nuclear industry is littered with costly failures to create advanced reactor designs that could economically and reliably do what Hansen and his colleagues think has already been accomplished by “modern nuclear technology”: “reduce proliferation risks and solve the waste disposal problem by burning current waste and using fuel more efficiently.”
Finally, the open letter suggests that that it is the environmental community that is somehow holding back a nuclear power surge. Nothing could be further from the truth. A U.S. “nuclear renaissance” has failed to materialize, despite targeted federal subsidies, because of nuclear power’s high capital cost, long construction times, the lower demand for electricity due largely to improvements in energy efficiency and competition from renewables. Unless Hansen, et al. want the U.S. to join the society of planned economies, the better approach to which we can all agree is to internalize the cost of carbon emissions and let energy efficiency, renewables and nuclear compete on a level playing field. We and the Hansen group obviously disagree on who the winners are likely to be, but let’s not delay further in finding out.
NRDC is a long-time advocate for expanded research spanning a wide range of energy technologies. No one can or should close the door to the prospect of improved nuclear power technology. But in a world with constrained capital resources and an urgent need to find the lowest cost ways to cut carbon pollution, nuclear power ranks far down the list of promising or likely solutions. We hope that Hansen and his colleagues will keep their focus on the urgent need to reduce global greenhouse gas emissions, and let winners and losers in the clean energy race emerge on the merits.
